Title: Data gathering system housing/mounting
Inventor: NOJIRI HOWARD H
IPC: G01G23/00
Filed: 1990-03-23
Abstract: Abstract of the Disclosure Housing/mounting apparatus for a data gathering system inserted into a checkout counter and including a weighing scale and an optical scanner supported thereon for scanning bar code labels and defining an upper weighing surface of the scale comprises a base supported within the checkout counter for supporting the data gathering system with the scale being secured to the base.  A perimeter enclosure is secured to the base and houses the optical scanner.  The scale includes a spider load receiving plate supported within the perimeter enclosure through an aperture in its floor.  Locator pins and corresponding holes stably position the optical scanner on the scale load receiving plate and the optical scanner thus positioned is sized such that clearance gaps required for proper operation of the weighing scale are defined between the optical scanner and the perimeter enclosure.  Leveling and fastener or clamping devices are incorporated into the base to facilitate installation and maintenance of the system.  By incorporating these devices into the mounting base, the system can be positioned, leveled and secured in place after the base is installed in a checkout counter to eliminate iterative operations. Scanner height adjustments are performed and limits on scale travel are defined by devices incorporated into the weighing platter adding further to the versatility and ease of installation/maintenance of a data gathering system incorporating the housing/mounting apparatus.

Abstract: ABSTRACT         A continuous business form assembly is provided which comprises a continuous web incorporating a plurality of business forms, the business forms each having a window flap portion and a non-window, remainder portion, the form having an exterior surface and an opposite, interior surface.  The window flap portion has a first face defined on the web exterior surface and a second face defined on the web interior surface, the window first face and second face thereby being defined on the opposite exterior and interior surfaces of the form.       The window flap portion is partially cut from the form to thereby form a window at least partially defined by one edge providing a fold line about which the window flap portion is foldable along a fold line to a printing position in which the window flap first face is exposed with the interior surface of the form, for simultaneous, printing of the window flap first face and the interior surface of the form.  The window flap portion is foldable along the fold line, after printing, to a closed position in which the window flap first face is returned to exposure with the exterior surface of the form and acts as a label for the business form.  Each window is substantially covered by a transparent patch mounted to the interior surface of the form, the patch defined by four edges, a first of which is located substantially along the fold line of the window flap portion.

Inventor: SINGEWALD ARNO
IPC: B03C7/12
Filed: 1990-06-27
Abstract: A process and a device is disclosed for the electrostatic separation of mineral mixtures, especially raw potassium salts, in a free fall separator, into a coarse fraction and a fine fraction, after the ground-up mixture has been conditioned and electrostatically charged. Each of the fractions is separately electrostatically processed and the fine fraction is fed to a free fall separator where a vertical air flow is generated in the direction from the inlet to foot of the separator. To generate the air flow, tubes or annular pipes made of electrically non-conducting material, are arranged in the discharge ducts of the free fall separator. These devices have nozzle openings oriented towards the foot of the separator and they are connected to a device which generates a negative pressure.
Patent CA-2020522-A1 (CA)
Inventor: BEALKOWSKI RICHARD
IPC: G06F9/445
Filed: 1990-07-05
Abstract: An apparatus and method for loading BIOS from a diskette drive (66) into a personal computer system (10) normally connected to a fixed disk drive (62). The personal computer system (10) further includes a system processor (26), a random access main memory, a read only memory (36) and a switching means. The switching means generates a signal to indicate a mode for whether BIOS loads from either diskette or disk. In a priority mode, BIOS loads immediately from diskette. In a recovery mode, BIOS loads from diskette after testing the disk subsystem. The read only memory (36) includes a first portion of BIOS and data representing the type of system processor (26) and system planar (24) I/O configuration. The first portion of BIOS initializes the system (10) and queries the switching means. If the fixed disk is not available or the master boot record on the disk is invalid, the first portion of BIOS reads in a master boot record from the diskette drive (66). For either mode, the master boot record includes a data segment (122-138) and an executable code segment (120). The data segment (122-138) includes data representing system hardware and a system configuration which is supported by the master boot record. The first BIOS portion transfers control to the executable code segment (120) which confirms the master boot record is compatible with the system hardware by verifying that the data from the data segment (122-138) of the master boot record agrees with the system processor (26), system planar (24), and planar I/O configuration. If the master boot record is compatible with the system hardware, the executable code segment (120) confirms that the system configuration has not changed and loads in the remaining BIOS portion from the diskette drive (66) into random access memory (32). The executable code segment (120) then verifies the authenticity of the remaining BIOS portion and vectors the system processor (26) to begin executing the BIOS now in random access memory (32). BIOS, executing in random access memory (32), then boots up the operating system to begin operation of the personal computer system (10).

Inventor: MCCANDLESS JAMES C
IPC: F02D9/04
Filed: 1990-09-21
Abstract: An exhaust back pressure control system includes a valve in the exhaust outlet of a turbocharger of an internal combustion engine which is controlled by an engine control microcomputer. When the valve is moved toward a closed position, it restricts the exhaust flow, thereby increasing back pressure and friction within the engine by producing an artificial load thereon, and thus speeds up the warming process taking place within the engine upon starting thereof. The valve is moved by an actuating piston within a hydraulic cylinder using engine oil pressure controlled by an electrically operated valve receiving a pulse width modulated operating signal from the engine microcomputer, the operating signal being generated to provide a desired back pressure as a function of engine coolant temperature, engine speed, engine fuel consumption, and actual back pressure. Operation of the system is enabled if the ambient air temperature is below 2°C and also for the period that the elapsed time since start of engine is less than thirty seconds, the latter enablement being provided to exercise the system during extended periods of warm weather operation when the system would otherwise be inactive.

Abstract: A flexible burn dressing product contains a hydrogel material in a gel-like phase. The burn dressing product is comprised of several layers including a burn dressing and a release layer. The burn dressing is comprised of a bacterial barrier layer coated with a bonding layer, a reticulated layer impregnated with a hydrogel material, and a hydrogel material layer. A dimensionally stable backing member may also,be adhesively attached to the bacterial barrier layer to help the burn dressing maintain its shape until it is applied to a patient. When the burn dressing product is to be applied to a burn site, the release layer is removed to expose the hydrogel material layer. The remaining layers of the burn dressing product are then applied to the burn site, with the hydrogel material layer directly contacting the burn.      Once these layers are in place, the dimensionally stable backing member is removed.
